Abstract:

Article concerns economic and energy efficiency of agriculture in European Union countries. The study period concerned 2016. For analysis and presentation of materials, descriptive, tabular and graphic methods and the Data Envelopment Analysis (DEA) method – CCR (Charnes, Cooper and Rhodes) model focused on input-oriented minimisation were used. An assessment of the socio-economic development of the EU countries was made using the following measures: Human Development Index (HDI) and Gross Domestic Product (GDP) per capita (USD per inhabitant). Modern agriculture depends on industrial energy sources and as the socio-economic development changes into more and more energy-intensive production technologies. After presenting the introduction and review of the literature, the economic and energy efficiency of agriculture in the EU countries in 2016 was examined, which was at a high level – the DEA reached 0.67. Then, the correlation between the socio-economic development of countries and their economic and energy efficiency was analysed. It was also found that along with socio-economic development in the EU countries, the economic and energy efficiency of agriculture is increasing.

Abstract:

This study delves into the multifaceted landscape of energy efficiency management with the objective of rationalizing the utilization of energy resources. The article considers a methodical approach to the study of the level of energy intensity of economic activity, covering levels of management, from the macro level to the level of an individual enterprise. In general, it is advisable to supplement the proposed approach with existing methods that extend the content to the results of energy efficiency research. Using the Life Cycle Assessment (LCA) method and other methodologies, we explore various dimensions of energy resource utilization and the scale of energy efficiency management across different stages of the lifecycle. Additionally, the study introduces levels of energy efficiency management developed by the authors, providing a structured framework for optimizing energy use. Through rigorous analysis, we evaluate the environmental impacts, energy consumption patterns, and efficiency levels associated with diverse energy management strategies. Our findings illuminate key areas for improvement and optimization in energy utilization practices, offering insight beneficial for policymakers, industry stakeholders, and environmental advocates alike. By leveraging the comprehensive framework of LCA alongside the developed levels of energy efficiency management, this research contributes to a nuanced understanding of energy efficiency management, thereby facilitating informed decision-making towards sustainable energy utilization pathways. Examining the example of building the life cycle of gas production and highlighting the main stages of its transformation from a raw resource to a finished product for consumption allows for the consideration of the entire chain of creation of the added value of this energy resource and enables control of the level of its influence on the results of the activities of economic units involved in this chain, as well as the consequences of their impact on the environment. This allows us to conclude that the approach discussed in the article can be used both for researching the energy efficiency of individual enterprises, as well as their associations, industries, and the economy in general.

Abstract:

Global economic growth is accompanied by increased energy demand, thus conventional fuels such as coal, oil and gas, which are the primary energy sources, are gradually being depleted. At the same time, the combustion of conventional fuel for energy production causes serious adverse effects on the environment and contributes to climate change due to the emitted greenhouse gases. For the above reasons, most of the developed and developing countries especially during the last decades, have introduced various incentives for the greater penetration of renewable energy sources (RES) in all sectors of the economy. Concerning the building sector, several measures have been adopted, including the promotion of energy efficiency and energy saving. A significant proportion of the building stock are the school buildings where students and teachers spend a significant proportion of their daily time. Teachers' attitudes and views, especially the school unit managers concerning the use of RES in schools, are important in the effort to rationalize and control energy use. This study was conducted through a structured questionnaire applied to a sample of 510 school managers in Greece's primary and secondary education. The school unit managerial role for the case of Greek schools is performed by the school principal who has both administrative and educational duties. Statistical analysis included the application of Friedman's test and hypothesis test on questions concerning school manager environmental perceptions and energy-saving habits. According to the results, Greek school managers have a high degree of environmental sensitivity, since 97.6 % agreed or strongly agreed that the main concern should focus on energy saving. Furthermore, 71% of the respondent reported to have good knowledge on solar energy, followed by 64% on wind energy while only 34% are knowledgeable on biomass. Almost all the respondents (99%) agreed that it is important to provide more RES-orientated education through the taught curricula. Concerning energy saving behaviour, around 90% reported that they switch off the lights when leaving the classroom and they close the windows when the air-condition is operating. Hypothesis tests revealed a relationship between the school managers' ecological beliefs, the energy saving habits in the school environment, and the recognition of the importance of environmental education. Conclusions highlighted the need to intensify environmental education programs in the school environment concerning RES in schools. This will lead to a higher level of environmental awareness of both teachers and students and therefore to a more dynamic behaviour towards the effort to “greenify” the school environment.

Abstract:

<p>Nowadays, the increased demand for energy and electrification associated with higher production costs from renewable and cleaner sources has driven up prices, impacting the industrial, commercial, and residential sectors. With a direct influence on the development of these economic sectors, its direct and indirect impacts to products and services have become important to find more efficient ways and best practices on energy use to support sustainable development. Aiming to shed light on this topic, and how individuals and society behave in this energy market transformation, this article explores opportunities for reducing electricity consumption through the use of modern technologies, such as of monitoring, optimization, automation, and adjustment of routines. At the same time, it is also our intention to bring to the surface a discussion around the rational use of everyday resources and raising the awareness of its impact to individuals and institutions. At its core, this work consists of continuous data collection of single devices and equipment in regard to status, energy consumption, and other relevant data of a typical household. Through behavioral changes and introduction of smart home automation techniques, it was possible to trace a parallel comparison between different scenarios and their influence on the energy consumption without negative impact to the comfort of individuals. Seeking a continuous improvement approach, extensive iterations were conducted, and it was possible to notice not only an energy efficiency improvement, but at the same time gains in living standards and safety. The significant results observed over subsequent months and years highlight not only practical and financial benefits, but also increased awareness and behavioral changes toward the rational use of electricity in households.</p>

Abstract:

Improving the energy-efficiency of computing systems has been the focus of computer science research for many decades. In the data center domain, for example, there has been an intense focus on improving energy efficiency by improving the Power Usage Effectiveness (PUE) of data centers. Other domains such as civil and mechanical engineering have also focused on improving the energy efficiency of built environments such as buildings. More recently, there has been an increased emphasis on sustainability on the human-built infrastructure of various kinds motivated by climate change, which has resulted in an emphasis on reducing carbon emissions of such infrastructure by optimizing their carbon efficiency.

Abstract:

The recent surge in publications addressing household energy efficiency and renewable energy highlights their vital roles in managing national decarbonization and green power transition. The study aims to analyze the research trends in this field to comprehend their significance in shaping residential decarbonization changes. Bibliometric and visualization analyses are applied to bridge existing knowledge gaps by focusing on technology and managerial mechanisms for implementing energy efficiency and renewable energy concepts. Leveraging the Scopus database and VOSviewer 1.6.19 software, the study covers energy efficiency publications from 1978 to 2023 and renewable energy papers from 1984 to 2023. The study clusters academic articles in two ways: keyword co-occurrence and co-authorship analyses. The first one reveals the merging of renewable energy and energy efficiency studies, covering sustainable development, heating/cooling mechanisms, and emerging technology trends. While both topics share commonalities like smart grids and the Internet of Things, renewable energy clusters spotlight specific areas such as bioenergy and wind/solar power. Co-authorship analysis highlights a notable increase in countries considering research topics, reflecting growing international collaboration. Leading contributors include the United States, the United Kingdom, China, Germany, and India. This study equips scientists with a systematic understanding of the evolution and latest research trends in managing household energy efficiency and renewable energy transformations. It aids in identifying promising research directions, further advancing these crucial fields. AcknowledgmentsThe publication was prepared in the framework of the research project “Formation of economic mechanisms to increase energy efficiency and provide sustainable development of renewable energy in Ukraine’s households” (No. 0122U001233), funded by the National Research Foundation of Ukraine.

Abstract:

The decrease in the regulative power of states has generated a governance gap that has been filled by, among others, international standard-setting bodies. In these bodies, private technical experts shape the rules that govern commonly used technologies as well as influence various societal outcomes. The legitimacy of such regulatory outsourcing is largely based on a variety of quasi-democratic mechanisms and principles, which these bodies have endeavored to make central to the standard-setting processes. This paper examines these legitimacy-seeking aspirations by comparing the normative claims with the actual practice of developing the international techno-policy standard for TVs by the International Electrotechnical Commission, based on interviews with stakeholders and numerous public and internal documents. The findings suggest that the process is inadequate if the goal is not just to bundle technical expertise but also to meet the standards of democratic governance. The study thus contributes to the literature on standard-setting and legitimacy beyond the nation-state.

Abstract:

There is a global consensus relevant to consequences of inactivity on the mitigation of negative effects of the climate change. Clear tasks with measurable results that should be implemented in the specified time are also well known. The preparation of an energy policy is faced with strict constraints that require innovative approach throughout the whole cycle of policy making process, whereas particular attention has to be given to its implementation. Globally observed, energy efficiency is the best and the fastest way to reduce GHG emissions in the medium term. Energy efficiency should be observed as the means for curbing the exploitation of natural resources. The increase of energy efficiency towards the point of theoretical maximum requires new technical improvements and the establishment of economic environments that stimulate such a trend. In this paper, technical and economic potentials of energy efficiency are evaluated. Also, activities for the correction of energy policies are specified in order to achieve faster and better effects on lowering exhaustion of natural resources and reducing GHG emissions.

Abstract:

Answers to the question ‘what should we do to improve energy efficiency?’ will have to advance beyond the notion of simply ‘saving energy’ to an enhanced paradigm of policy options as cross-sectoral issue. In this paper we propose to improve rate of successfully performed energy efficiency project. In order to reach target, we need to study and summarize the best practices of improving the energy efficiency level within the economy for developing recommendations, to create risk model for modifying energy policy approaches and working processes with an abstraction level increase for the successful energy efficiency projects realization. Two issues have been addressed in this paper. The links between sustainable development concept analysis and “Green Economy” are defined. The key factors for the sustainable development of energy policy intended for the development of successful energy efficient projects while improving energy efficiency and environmental safety are identified.

Abstract:

Abstract This article aims to carry out a comparative analysis in the European Union and in Romania, in the period 1991-2021, on the achievement of the ambitious energy efficiency objectives, by assessing the achievement of the assumed targets for primary and final energy consumption at the level of the years 2020 and 2030. Since 2007, EU leaders have been concerned about the decarbonisation of the energy sector, a first essential measure being to reduce energy consumption by 20% by 2020. As part of the decarbonisation objectives for 2050, we start from this premise, according to which energy efficiency must be improved, thus accelerating the transition of all member states of the European Union to clean energy and sustainable growth of economies. So, by using energy more efficiently and therefore consuming less, we can contribute both to protecting the environment and to mitigating climate change. The hypothesis from which we start in this study is that the target for 2020 of the level of primary and final energy consumption has been met, due to the negative effects of the COVID-19 pandemic. In order to test this hypothesis, Eurostat data were analyzed using the quantitative research method for both the European Union and Romania. As a result of the analysis carried out, this hypothesis can be fully confirmed, since from 2021, which coincides with the beginning of the recovery of economies, an increase in primary and final energy consumption can be observed again, after a sharp decrease in 2020, even below the level of the targets set for 2020. With regard to the targets assumed by the European Union for 2030, the consumption of primary and final energy is well above the predetermined values. And the conclusions show us with certainty, the need to make an additional effort in order to achieve them.

Abstract:

In this paper, we show a case study of Ryzen processor energy efficiency using SPECjbb2015 as the workload. We analyze it in comparison to Phenom II, a CPU of previous generation from the same manufacturer AMD. In terms of maxi-mum transaction throughput, Ryzen performs 218% of Phenom. With the response time constraint, the relative performance of Ryzen is 288%. In the energy efficiency, Ryzen achieves 309% (at maximum throughput) and 389% (with response time constraints) of Phenom. Dynamic frequency scaling (DFS) is effective for reducing the power consumption of both processors, but the load levels at which DFS is most effective are quite different.

Abstract:

Environmental pollution is one of the major problems that has become an increasing area of concern globally, leading to the emergence of green energy technology. Research has been conducted on green technology adoption mainly in developed countries. However, there is noticeably limited knowledge about technology adoption and energy consumption in developing countries, for example, Zimbabwe. Thus, this paper seeks to analyze the impact of green technology adoption on energy sector performance in Zimbabwe. The results established that green technology adoption, energy pricing, energy sector investment, and capital structure significantly influence energy consumption efficiency. These results showed a positive relationship between green technology adoption and energy consumption efficiency based on the argument of the substitution possibility effect between green technology and energy demand. The study recommends adopting and identifying the type of green technology to utilize and the timing of investment in green technology. In addition, alternative estimation methods can be adopted to test the robustness of the findings.
